Efforts to trap early intermediates of the gold-catalyzed phenolsynthesis failed. Neither inter- nor intramolecularly offered vinyl groups, ketones or alcohols were able to intercept the gold carbenoid species. This indicates that the competing steps of the gold-catalyzed phenolsynthesis are much faster than the steps of the interception reaction. In the latter the barrier of activation is higher
